ABSTRACT:
A turntable has a drive for rotating it. A vertical control rod extending up alongside the turntable carries a dancer arm adjustably mounted thereon. The strip coming off the supply coil trains over the spool. A variable electrical control is adjacent the control rod and influenced by its rotary position. The control relates the speed of the turntable to whether the arm is inward or outward--whether there is greater or less demand for the strip. In the preferred version, a bias for the control rod urges the dancer arm outward in dampened fashion but more readily permits the arm to be drawn inward.
